Fix build - close #39 and #42

[couzic]

As stated in #39 and #42 the current npm release (2.0.0-beta.2) has problems. This pull request provides a simple solution, based solely on npm and tsc. However, I ran into problems understanding the previous build system, so I happened to break it. I'm not sure how/where/if it is used, and it seems rather over-complicated, so I wondered if it would be possible to get rid of it completely.

@micouz the bundles folder is not being created with appropriate js and minified js files, which are used for publishing on cdnjs

@mohammedzamakhan Yes I missed that part. I'll add another commit to this PR.

for the demo to run using gulp play, I have changed the the dest folder to demo in the task ts2js and I see an error which I didn't see in the demo:

Can you also make sure that demo works fine with all your changes.

Thanks

I couldn't reproduce your error, but I had another one of my own. I then tried with a clean checkout of the branch, and for me everything works fine. Could you try again and give me the sequence of steps you take when you see the problem ?
Right now I'm concentrating on getting this PR merged to close the npm release issues, but in the not so distant future I'd like to improve the demo dev environment, using webpack-dev-server.
